For general information on tumor imaging, see a review of MRI principles (Hesselink) and the Wikipedia articles on medical imaging, MRI, MRS, and PET.  For a review of new approaches to tumor imaging, focusing on monitoring response to treatment, see Brindle 2008.

The following papers provide information on imaging specifically related to brain tumors:

• Henson et al 2008 reviews brain tumor imaging in clinical trials.
• Smirniotopoulos et al 2007 reviews patterns of contrast enhancement.
• Brown et al 2003 reviews several brain tumor case studies.
• Harrison reviews several brain tumor case studies.
• Brandsma et al 2008 reviews pseudoprogression in malignant gliomas.
• Brandes et al 2008 discusses use of MGMT promoter methylation status to help identify pseudoprogression in GBM.
• Danchaivijitr et al 2008 reviews perfusion-weighted MRI as a means for early detection of malignant transformation of low-grade gliomas.
• Cunliffe et al 2009 reviews intracranial lesions which can radiologically and/or clinically mimic tumors, resulting in unnecessary surgical biopsy or resection.
